Heavy Rainfall Outlook
Forecast accumulated rainfall on Wednesday
Above 200 mm: Apayao and Abra
100-200 mm: Mt. Province, and Benguet
50-100 mm: the rest of Cordillera Administrative Region
Forecast accumulated rainfall on Wednesday noon to Thursday noon
Above 200 mm: The northwestern portion of Abra
100-200 mm: Apayao and the rest of Abra
50-100 mm: Kalinga, the western portion of Mountain Province, and Benguet
Forecast rainfall are generally higher in elevated or mountainous areas. Under these conditions, flooding and rain induced landslides are highly likely especially in areas that are highly or very highly susceptible to these hazard as identified in hazard maps and in localities that experienced considerable amounts of rainfall for the past several days.
In addition, EGAY may also enhance the Southwest Monsoon, bringing occasional to monsoon rains over the western portions of Central Luzon, Southern Luzon, and Visayas in the next three days.
Severe Winds
Minor to moderate impacts from gale-force winds are possible within any of the areas where Wind Signal No. 2 are in effect.
Minimal to minor impacts from strong winds are also possible within any of the areas where Wind Signal No.1 is hoisted.
Current forecast scenario shows that the highest wind signal that may be hoisted will be Wind Signal No. 4 or 5 (e.g., typhoon-force wind threat).
EGAY and the enhanced Southwest Monsoon may also bring gusty conditions over the following areas not under any Wind Signal, especially in coastal and upland/mountainous areas exposed to winds:
Today: The rest of Visayas and MIMAROPA, and the northern portions of Zamboanga Peninsula, Northern Mindanao, and Caraga.
Tomorrow: The rest of Luzon and Visayas, Zamboanga Peninsula, Basilan, Sulu, Tawi-Tawi, and the northern portion of Northern Mindanao and Dinagat Islands.
Wednesday: Visayas and the rest of Luzon.
TRACK AND INTENSITY OUTLOOK
EGAY is forecast to track north northwestward in the next 12 hours before turning generally northwestward and head closer to the landmass of Northern Luzon towards the Luzon Strait.
On the track forecast, this typhoon is forecast to cross the Luzon Strait and make landfall or pass very close to the Babuyan Islands-Batanes area between tomorrow late evening and Wednesday morning. Typhoon EGAY may exit the Philippine Area of Responsibility (PAR) on Thursday as it moves over the waters southwest of Taiwan.
Outside the PAR, the typhoon will cross the Taiwan Strait and make landfall over Fujian, China on late Thursday or early Friday. • It must be emphasized that further shift in the track forecast closer to Luzon remains a possibility due to the persistence of the ridge of high pressure north of the typhoon. This is represented by the forecast confidence cone. As such, a landfall over the northeastern portion of mainland Cagayan is not ruled out.
EGAY is forecast to continue intensifying and reach super typhoon category by late tomorrow or on early Wednesday. However, should the track forecast shift closer to the landmass of Luzon, the typhoon may peak at an intensity just below STY threshold. Nevertheless, EGAY is forecast to become a very strong typhoon. A weakening trend may begin by Wednesday afternoon or evening as it enters the cooler waters southwest and west of Taiwan (i.e., Taiwan Strait)
Considering these developments, the public and disaster risk reduction and management offices concerned are advised to take all necessary measures to protect life and property. Persons living in areas identified to be highly or very highly susceptible to these hazards are advised to follow evacuation and other instructions from local officials. For heavy rainfall warnings, thunderstorm/rainfall advisories, and other severe weather information specific to your area, please monitor products issued by your local PAGASA Regional Services Division.
